Don't re-encode, you'll only lose quality & time. Since you can play
MP3 anywhere, there's no real need to do this.

RC1 encoder will be released when Monty think it's ready. :-)
Probably in July or August.

MvK> good is the 1.0 decoder if I can't have channel-coupled encoding?

Decoder was released so that companies which implement Vorbis
don't have to upgrade in the future.

Well I would suggest to wait for at least RC1, but that really depends
on whether you are satisfied with current quality/compression ratio
and with encoding options that oggenc has right now. Since RC1 will
appear soon (in a month or two), I suggest you wait.

-b256 mode is transparent for almost all songs I have tried. Even
though there are still some bugs in this mode, I think it is very
near archive quality. Still, for massive encoding I would suggest
waiting for RC1 to come out since this will happen soon.
